Foregut-Origin Ciliated Cyst of the Gallbladder

Abstract

oregut-origin ciliated cysts origin may occur in relation to the tracheobronchial tree to upper digestive tract. 1 Ciliated foregut cysts are rare anomalies due to aberrant embryological development. It is thought to arise from a remnant of the embryologic foregut. The solitary cysts are characterised by ciliated pseudostratified columnar epithelium. 2,3 Foregut cysts below the diaphragm usually occur in the liver. 4 Herein, we present a case of foregut-origin ciliated cyst of the gallbladder. CASE REPORT A 69-year-old male patient was admitted to our hospital's surgical polyclinic with symptoms of abdominal pain, which he had had for the last 3 years. Tenderness of the right upper quadrant and Murphy's sign were present but rebound tenderness was not present in the physical examination. The results of laboratory examinations indicated normal alanine transaminase (ALT) and aspartate aminotransferase (AST) enzymes. Serologic tumor markers (AFP, CEA and CA19-9) and hepatitis B and C markers were negative. He was sent to the radiology clinic for ultrasonography (USG) of the abdomen, which revealed gallstones and a benign-appearing cystic lesion on the fundus of the gallbladder (Figure 1). A cystic structure adjacent to the gallbladder wall was found on abdominal computed tomography (CT) (Figure 2). The operation has been planned for the patient and admission to the service has been pro
